The 1978 Maserati Merak sits in the era when Italian grand touring cars blended exotic styling with real road-going usability. Its mid-engine layout and Citroen-era engineering give it a distinct personality, and tire fitment matters because the car uses a staggered setup rather than the same size at all four corners. A 195/70R15 radial is used in front, while the rear uses a 205/70R15 radial on a 15-inch rim. That opens the door to choices ranging from Michelin XWX performance-oriented blackwalls to whitewall and bias-look radial options in the rear size. Selecting tires for a Merak means balancing proper front-to-rear fitment, appearance, and the kind of driving the car will actually see.
Which Tire Size Is Right for The 1978 Maserati Merak
The 1978 Maserati Merak uses two primary tire sizes, both in radial construction on 15-inch rims. The key is identifying position first, because the front and rear do not share the same size: 195/70R15 belongs on the front, while 205/70R15 is used on the rear. Once that is confirmed, the decision becomes choosing the right tire style, brand, and series for the way the car is being restored or driven.
195/70R15 is a metric radial size in which 195 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. On the 1978 Maserati Merak, this size is used at the front, where maintaining the intended front tire fitment is important to the car's overall setup. Michelin XWX is available in this size with a blackwall presentation that suits a traditional European performance look. This is the size to evaluate when the goal is preserving the Merak's correct front tire proportions on a 15-inch wheel.
205/70R15 is a metric radial size with a 205-millimeter nominal section width, a 70-series profile, radial construction, and a 15-inch rim diameter. On the 1978 Maserati Merak, this size is used at the rear, making it the key choice for the car's staggered back-wheel fitment. Rear tire options include blackwall, narrow whitewall, wide whitewall, and even a bias-look radial, with brands such as Michelin, Avon, Dunlop, Maxxis, American Classic, Tornel, Travelstar, and Coker Classic represented across several series. This is the size to focus on when selecting the Merak's rear tire appearance and road-use character.
Fitment on the 1978 Maserati Merak is straightforward once tire position is confirmed, but front and rear sizing are different. Checking the exact sub-model designation matters here because the covered front and rear fitments do not use the same tire size.

1978 Maserati Merak Base Front
The 1978 Maserati Merak Base Front uses a 195/70R15 radial tire on a 15-inch rim. That makes the front selection less about multiple size choices and more about keeping the correct front fitment and choosing the tire style that suits the car's intended presentation.
The 1978 Maserati Merak Base Rear uses a 205/70R15 radial tire on a 15-inch rim. Rear tire selection offers more variety, so the choice often comes down to whether the car needs a blackwall performance look, a whitewall treatment, or a bias-look radial presentation.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 1978 Maserati Merak?
The 1978 Maserati Merak uses two tire sizes rather than one uniform fitment. The front uses 195/70R15, and the rear uses 205/70R15, with both sizes built around radial construction and 15-inch rims.
That means the first step is confirming whether the tire is for the front or rear of the car before comparing products. A Merak with replacement wheels or prior modifications should also have wheel width, overall tire dimensions, and body or suspension clearance checked so the staggered setup remains appropriate.
What size rim does a 1978 Maserati Merak use?
Both primary tire sizes for the 1978 Maserati Merak are built for 15-inch rims. The front 195/70R15 and rear 205/70R15 share the same rim diameter, even though the tire widths and overall roles on the car differ.
Rim diameter is only part of the fitment picture, so confirming wheel width still matters before selecting a tire. That becomes especially important on the rear size, where available products have different rim-width specifications and the car may have seen wheel changes over time.
Do all 1978 Maserati Merak sub-models use the same tire size?
The covered 1978 Maserati Merak fitment does not use one tire size across every position. The Base Front uses 195/70R15, while the Base Rear uses 205/70R15, so front and rear fitment are intentionally different.
That distinction matters because choosing by year, make, and model alone is not enough on this car. A buyer should confirm position on the vehicle, then compare the selected tire against the actual wheel and the space available around the suspension and body before making a change.
Choosing the Right Tire
What should I consider when choosing a 205/70R15 tire for a 1978 Maserati Merak?
Start with the fact that 205/70R15 is the rear tire size on the 1978 Maserati Merak. From there, the most meaningful differences are construction style, sidewall treatment, brand, tire series, and whether the tire's rim-width specification suits the wheel on the car.
Rear options range from blackwall European-style performance tires to narrow whitewall, wide whitewall, and bias-look radial presentations. The best choice depends on whether the Merak is being kept visually traditional, shown, or driven regularly, while still respecting wheel compatibility and rear clearance.
What sidewall styles are available for 1978 Maserati Merak tires?
Sidewall choices for the 1978 Maserati Merak include blackwall, narrow whitewall, and wide whitewall, depending on tire size and product line. The front 195/70R15 offering centers on a blackwall Michelin XWX, while the rear 205/70R15 size has the broadest variety.
That gives the rear tire a strong influence on the car's finished appearance. A blackwall keeps the look closer to a European performance presentation, while narrow or wide whitewalls move the visual character in a more customized or classic direction, so sidewall style should be chosen deliberately rather than by size alone.
What brands offer tires for the 1978 Maserati Merak?
Tires for the 1978 Maserati Merak are available from Michelin, Avon, Dunlop, Maxxis, American Classic, Coker Classic, Tornel, and Travelstar. Brand variety is concentrated most heavily in the rear 205/70R15 size, while the front 195/70R15 fitment is represented here by Michelin XWX.
Brand choice should be treated as part of a larger fitment decision rather than the only deciding factor. Comparing tire series, sidewall style, rim-width compatibility, and the kind of look or road use the car needs will usually narrow the field more effectively than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1978 Maserati Merak?
A period-style 1978 Maserati Merak tire choice starts with keeping the correct front and rear sizes in place: 195/70R15 up front and 205/70R15 in the rear. Within that framework, blackwall designs such as Michelin XWX and other blackwall rear options preserve a more traditional European grand touring appearance.
Appearance goals should guide the final choice after fitment is settled. A Merak being restored with close attention to era character usually benefits from careful attention to sidewall presentation and tread style, while buyers pursuing exact originality should also compare against marque references and vehicle-specific historical documentation.
How does tire construction affect the appearance of a restored 1978 Maserati Merak?
The 1978 Maserati Merak uses radial tire sizes as its primary fitment, so the visual decision is less about switching from bias-ply and more about choosing the radial style that suits the car. Blackwall radials deliver the most restrained performance-oriented look, while whitewall and bias-look radial options change the presentation noticeably.
Construction details can influence how authentic or stylized the finished car appears, even when the size is correct. A restoration-oriented Merak usually benefits from matching the tire's sidewall character to the car's intended era impression, rather than treating any available 15-inch radial as visually interchangeable.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1978 Maserati Merak?
Yes, modifications can affect tire fitment on a 1978 Maserati Merak even when the nominal tire size remains 195/70R15 in front and 205/70R15 in the rear. Changes to wheel width, wheel offset, ride height, springs, or body clearance can alter how those tires sit and move on the car.
A Merak with aftermarket wheels or suspension work should be checked carefully before assuming a familiar size will behave the same way. Steering clearance at the front and body or suspension clearance at the rear deserve special attention, particularly because this car does not use the same tire size at both ends.
What should I inspect before driving a 1978 Maserati Merak on new tires?
Before driving a 1978 Maserati Merak on new tires, inspect the wheels for correct diameter and condition, confirm the front and rear sizes are mounted in the right positions, and check for adequate clearance around suspension, steering, and bodywork. Tire pressure should also be set appropriately and verified after installation.
Collector cars often spend long periods parked, so a road-ready inspection should extend beyond the tires themselves. Looking for fluid leaks, worn suspension parts, uneven wheel movement, and any signs of rubbing during low-speed steering or compression can help prevent a new tire from being compromised early.
How should 195/70R15 and 205/70R15 tires on a collector 1978 Maserati Merak be maintained?
Collector-car tire maintenance on a 1978 Maserati Merak starts with regular pressure checks, routine visual inspection, and confirming that front 195/70R15 and rear 205/70R15 tires remain in good condition despite limited mileage. Sidewall cracking, flat spotting, cuts, bulges, and unexplained air loss all deserve attention.
Storage conditions matter almost as much as road use on a low-mileage Merak. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires, while periodic movement and inspection reduce the chance that age-related issues go unnoticed between drives.
